部队作战效能综合评估法

高技术条件下局部战争的显著特点是参战单位多、对抗关系复杂、战争不确定因素增加,如何在此情况下客观评估部队的作战效能是作战研究领域一个重点和难点。通过综合运用定性分析法、网络分析法、战斗效能指数法、作战模拟及系统动力学等多种方法和理论,建立了一种可对部队作战效能进行评估的综合评估法。并以高技术条件下岛上进攻作战中装甲团的作战效能评估为例,详细介绍了该方法的实施过程,认为该综合评估法是行之有效的。     

装备维护系统效能评估人素系数的建模与分析

传统的系统效能评估模型中,一般不考虑人的因素。然而,在国内外航空装备的维护过程中,由于人为失误引起的系统故障却占了相当大的比重。提出对人机系统效能评估的改进模型,并建立了装备维护系统效能评估中的人素系数模型,通过对人的可用性、可信性及固有能力的分析,得出了人素系数的确定方法。此系数的确定使航空装备维护管理部门能够更合理地进行装备维护系统的效能评估,有利于更好地组织配置人力资源。

编队对潜防御及效能评估

针对编队对潜防御的主要任务和基本原则,对编队防潜区域的划分和兵力部署进行了论述,并对编队防潜效果进行了定量计算.运用概率论知识建立了模型算法,以完好警戒舰艇数的数学期望和警戒兵力摧毁攻击潜艇的概率为效能评估指标,经定量计算得出了编队对潜防御时所需警戒兵力的数量及对潜艇的毁伤概率,并用被警戒舰艇的生存概率表征编队总的防潜效果.该模型为我海军编队防潜训练提供了理论依据,较好地满足了海上编队对潜防御兵力运用需求.

Pareto-optimality in classical inventory problems

In this paper the inventory problem with backorders both deterministic and stochastic is studied using trade-off analysis in the context of vector optimization theory. The set of Pareto-optimal solutions is geometrically characterized in both the constrained and unconstrained cases. Moreover, a new way of utilizing Pareto-optimality concepts to handle classical inventory problems with backorders is derived. A new analysis of these models is done by means of a trade-off analysis. New solutions are shown, and an error bound for total inventory cost is provided. Other models such as multi-item or stochastic lead-time demand inventory problems are addressed and their Pareto-optimal solution sets are obtained. An example is included showing the additional applicability of this kind of analysis to handle parametric problems. © 1998 John Wiley & Sons, Inc. Naval Research Logistics 45: 83–98, 1998     

EU security sector reform in Bosnia and Herzegovina: Reform or resist?

ABSTRACT

Attempts to explain the failure to reform the security sectors in post-conflict countries have often resorted to two sets of explanatory factors: international and local factors. This article seeks to move from that unhelpful dichotomy to an explanation linking both factors. Drawing on a Foucauldian approach and the concept of “counter-conduct,” it examines the rationality and practices of European Union (EU) governmentality and how governing technologies are resisted and reversed by local elites involved in security sector reform (SSR). Instead of understanding power and resistance as binary opposites, this article argues that counter-conduct can be conceived as implicated in the very relations of power that it seeks to resist. To tease out these relations, the article analyzes the EU's efforts in SSR in Bosnia and Herzegovina, where it identifies four forms of counter-conduct: upholding European standards, using the local ownership trap, simulating reforms, and lowering the bar.
